FNB power surge explanation questioned

Hopefully they werent covering up something else.
 
The type of fast monitoring required to log a typical surge, like a lightning strike, would not likely be found to UPS equipment

This.

To record a typical surge event, you would need to be sampling hundreds or even thousands of times per second. Such equipment has not historically been so cheap that you just connect it and leave it in place permanently. It is more often something that you rent for the occasion that you need it, and return it when you are done. As a result, it is extremely unlikely that the DC was commissioned with a monitor like this in place.

That said, a bit of googling shows that the price for such equipment has come down a LOT in recent years, to the order of $5000 or so. So it is plausible that FNB might have added something like this more recently. Previous power quality issues might have triggered the need for such a device, which might explain how they are able to quote the figures that they have.

Ja, PR prob screwed up the units, I am going to believe FNB's version a LONG time before City Power - who has a better track record of delivery and communication...

Chris Yelland – an electrical engineer and energy analyst - said "They (FNB) are talking absolute nonsense."

I will rather believe an electrical engineer than a banker CEO trying to protect his ass!!
FNB is now lying to its customers.
Shocking!

And in breaking news Chris Yelland - an electrical engineer and energy analyst - states JB has the cheapest and most reliable power in the world. He is an engineer working for City Power, why would he spin?

FNB have built up a huge amount of goodwill by being fairly open about stuff and communicating with their customers. City Power does not exactly have the same record hence me saying I will take FNB's word on it for now, perhaps I should have added until further evidence is provided.

I don't know if you are aware of how unstable power is SA is and how much damage it causes to electrical equipment on a regular basis.
 
Surely a power spike would have been filtered out by their UPS systems? Obviously if the spike was big enough it would damage the UPS, but still, that is not a whole data centre?
